I have a couple of old Raspberry Pi 1Bs and was going to repurpose it for something simple. I decided to make a new flash drive for it using the latest Raspbian Stretch Lite image 2018-04-18. The flash drive seems to be written correctly, but when I try to boot the image, it gets stuck right after the keyboard detection on the line:
[ 40.046049] random: crng init done
Then it just sits there indefinitely (have waited several minutes). I've tried a few different power supplies and cables to be sure. All I have hooked up is a keyboard and HDMI display. I've also confirmed that the Pi itself still works as I was able to boot to an older Raspbian version on a different flash card. Could be the flash card to I guess.
But just to confirm, will the latest Raspbian images work with the older Pi 1s?

on your SD card, make sure you check writing as well as reading ability, because likely your card may be corrupted.
